To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I don't know what makes Kérastase oil better than other ones but it leaves my hair in such lovely condition. I have long, thick, dry, wavy hair which is unruly due to years of highlighting. Whenever I think I'll save some money and get a cheaper oil or try something different, I end up regretting it and going back to this Kérastase one. It makes my hair so much softer and more manageable as well as smelling divine.
This is the best serum I have ever bought, the cheaper ones are nowhere near as good as this. I ran out of it for a couple of months and couldn't work out why my hair looked in such bad condition. After buying it again my hair has been transformed again! Brilliant product, makes hair so shiny, and smells lovely too.
This stuff is amazing and my hair feels great after using this I put some on wet hair before drying and sometimes I also use it after straightening or blow drying just to put through and it’s makes my hair feel so soft and shine and it smells great too
